Xbox Series X And PS5’s Raw Power Is Not As Important As How Devs Will Use It – The Initiative Dev

gamingbolt.com

The Xbox Series X and PS5 both have quite a lot going for them, and it’s clear that both consoles are emphasizing different aspects of their hardware in a bid to create next-gen experiences. The end result for both, however, is the same- they’re both looking like incredible pieces of machinery, and the potential of what developers might do with that is more than a little exciting.

In fact, The Initiative’s Senior Gameplay Engineer Francisco Aisa Garcia – who has previously worked at Naughty Dog and Rockstar – thinks that that is exactly the thing that’s going to define next-gen. We recently had a lengthy chat about the upcoming next-gen consoles – among other things – with Garcia, who’s currently working at Microsoft’s youngest first party studio, and when asked about whether he thinks the differences between both consoles will have any functional impact, he said that that impact will instead come from how developers use the hardware at their disposal.

“There is more raw power (referring to the Xbox Series X), that’s for sure, and you can push more when you have more power,” Garcia said. “But at the same time, ultimately, like you said, they are pretty evenly matched.

“I think the way you have to look at this is that there is a generation jump that is moving in the same direction for both consoles, I would even say this will apply to Nintendo. And it will come down not so much to the raw power they are going to have, but what the teams are going to do with that power. And I think they’re evenly matched because from an architecture point of view, both will allow the same kinds of fundamental changes to the way we do things in games.

“So I don’t think the big difference will be in how much more powerful it is, but rather in what we do with this new powerline.”

I've mentioned this many times already. Next gen systems are so freaking powerful, it's all up to developer talent now. The only thing holding them back is budget.

At the end of the 360/PS3 I remember devs saying that budgets were an issue and it was starting to cost too much to make big games and a lot of companies had to close shop for that reason.

I don’t think much has changed since, budget was and will always be an issue except for a few that can afford to spend the money and absorb the loss of sales don’t match expectations.

Ultimately it depends on the studio on how they utilize the hardware.

 

[kraspkibble]

Xbox has the faster CPU/RAM/GPU and a bit slower SSD
PS5 has the slower CPU/RAM/GPU and a bit faster SSD

SSD does not affect performance or visuals and only really improves loading times/streaming assets (pop in).

Xbox > PS5 in terms of performance when it comes to resolution/framerate. Of course yes it depends how it's used. if a developer builds a game to PS5 standards and doesn't bother taking advantage of Xbox then the extra power doesn't matter. just like how most developers will build games to the speed of the Xbox SSD so, again, games will run better on Xbox with better CPU/RAM/GPU and the SSD, although being slower, will still be just fine. the SSD will only benefit PS5 in 1st party games but if a studio is 1st party then they're obviously gonna get the most out of the hardware....

however the advantage is still in Xbox's favour because of the much faster speeds

Dont expect the Initiative game on July 23 show by the way. They only started in 2018.

Also, the average speed of the RAM is faster on PS5.

That is incorrect

All of PS5 memory is limited to 448GB/s whereas all of Xbox Series X 10GB reserved for GPU memory runs at 560GB/s, considerably faster than PS5.

Xbox Series X is designed to only use the 10GB pool for GPU memory, there will be no scenario where they will use an extra 1GB from the slower pool for GPU memory for example. The PS5 will have all 16GB to use wherever it sees fit, it's an advantage as opposed to splitting the ram in half and using for example 8GB of fast memory for GPU and 8GB of slower ram for everything else. On 360 it was an advantage because if a game needed 400MB of ram for GPU, it was a much easier scenario than PS3 which had to dig into 2 different memory pools when it exceeded 256MB, but MS cleverly reserved 10GB for GPU and just 6GB for audio CPU and OS, knowing that even with unified ram, they would likely end up with only 10GB for GPU once the OS and CPU+audio used up about 6GB.

 

[Ascend]

That this needs to be said at all is actually quite sad... The evidence is everywhere. In fact, there is one company that embodies this, and its evidence has been staring us in the face for years.

There's a reason Nintendo is still in business.

Actually MS has the slight edge over PS5 when it comes to ram.

There was no need for this post.

It just smacks of console warring and derails the thread.

Anyway. Next gen looking good no matter which console you choose. I can’t wait.

This isn't true. The PS5 technically has the faster GPU.

Technically that’s only due to “Variable frequency” and also the Xbox 52 compute units vs ps5’s measly 36.

The SSD does affect performance on visuals. How many games will benefit and how much that benefit will be on future has yet to be seen as the games are not made yet. Faster I/O reduces the chances of GPU/CPU idling or at least the overhead required to be more efficient because of slower I/O. The raw speed of the actual SSD isn't the only one part of why it is praised. There's extra custom silicone that is designed to eliminate bottle necks that reduce CPU and GPU usage in relation to retrieving data from the SSD. The SSD doesn't give you extra processing power it lets you possibly take advantage of more of the the raw theoretical that you normally can't fully access.

Also, if a developer can reliably rely on loading in a better texture they will have the opportunity to do so which can lead to better visuals. How perceptible that difference to the average user we don't know or what devs will do with third part games we don't know. But I don't think most people notice difference between 50fps and 60fps or if the game has to drop to 2k for 30 seconds either. I do think people will notice that a games loads right away. As for mobile phones, people seem to really enjoy how snappy everything feels on new phones when they shave off miliseconds.

In regards to the RAM, the SSD can act as a major bottleneck to the RAM depending on exactly what the game is trying to do. Having faster RAM can mean nothing if you are building your game to rely on pulling games from the SSD a lot "just in time" (which is even something Microsoft is advertising developers can now do). You are basically going to effectively get N amount of data available to the CPU as fast as the SSD goes instead of how fast the RAM goes. There's a reason it's called a bottleneck it's because no matter how big your bottle is, the size of the bottle neck limits the entire flow. So depending on how developers choose to develop their games in the future, you may see having a slower SSD bottle necking other components. But the XSX will still perform more efficiently working with data already in RAM.

This is why Epic praised the PS5 for being "balanced" because they added a lot of custom tech and focused on technologies to alleviate/remove bottlenecks.

The advantage is in nobody favor. It depends on how the game is created and what the developers are willing and can do. Because both companies have custom components and have different design choices altogether.

Now you just come off as a self-righteous schmuck.
You do make some valid points though. Therefore, I will mark it as No , that ship has sailed.

Okay, if we're going to ride with this analogy.

One of them is 10" on a good day. The other is 12" all the time.

Girls are going to be ecstatic with either one (but over twice as many will pick the first guy because he's simply more popular).

Your analogy would be a lot more accurate if you use Centimetres where 12 is barely enough and the rest will go PC

Analyse This: The Next Gen Consoles (Part 9) [UPDATED]

So, the Xbox Series X is mostly unveiled at this point, with only some questions regarding audio implementation and underlying graphics...

hole-in-my-head.blogspot.com

The SX has 2.5 GB reserved for system functions and we don't know how much the PS5 reserves for that similar functionality but it doesn't matter - the Xbox SX either has only 7.5 GB of interleaved memory operating at 560 GB/s for game utilisation before it has to start "lowering" the effective bandwidth of the memory below that of the PS5... or the SX has an averaged mixed memory bandwidth that is always below that of the baseline PS4 (must be a typo, PS5?)

Either option puts the SX at a disadvantage to the PS5 for more memory intensive games and the latter puts it at a disadvantage all of the time.

Thought that, by having a splitt one fast and one slower mempool .. as soon both are being accessed the effective speed of the faster mempools drops as both share the same bandwidth? but the use a different bus.

 

[ANIMAL1975]

Or 10 is barely enough, and the others will go pc that has the same 'game' as the 12 guy, but a bigger dick.

 

[pawel86ck]

Raw power is not everything, because developers can always use various tricks and gimmicks in order to achieve good results at much lower cost. UE5 is a good example, because lumen is not nearly as expensive as standard RT GI, yet it also looks very good.

GPU power will be however always important and that's the reason why UE5 tech demo run at sub 1440p and 30fps on PS5. Magician Cerny want to trick people into thinking ultra fast SSD will make PS5 games look like next gen compared to XSX / PC platforms and unfortunatelly many PS fans buy sony marketing. Some people even believe PS5 will run close to 2.2GHz even when Cerny has contradicted himself in the same video (luckily to him most people cant connect just two dots). I bet people who believe in PS5 marketing are the same people who believed PS4P will run games at 4K.

And time. AAA games are taking longer and longer to develop. Hope people are ready for GTA6 in...2022. And get ready to play that for a decade until GTA7

jakinov Good points but I think it's at least fair to also keep in mind the Series platforms benefit from all of the things you mention, with some parts in variance compared to PS5. Also there are still limitations to Sony's approach that have, to be fair, taken into consideration. For example the issue of bus contention with the I/O block accessing RAM for reads or writes, meaning the other processor components have to wait for bus access.

That doesn't get mentioned a lot and I feel it should be kept in mind because even with the obvious advantages PS5's approach brings that is one area I think the Series systems have an advantage ironically since it means CPU-bound game logic can still access the bus during I/O RAM access (with tradeoffs while doing so simultaneously of course).

You fell for the Sony spin and that’s hilarious. Xbox has the better GPU. Simple.

This same argument could have been used last Gen. But it wasn't. All we heard about was the power of the PS4. So yeah, not buying any of it even though its 100% true. I just don't like hypocrisy. No one gave the XBO the benefit of the doubt.

And most graphics ops have to use the fast pool. I think the split memory pool in the XSX and the ram design being asymmetrical will be a huge factor on why these consoles will be closer in performance than many believe

No question that both are quite potent machines and as the he states, it´s up to the devs to take advantage of it.

What serious bus access are you refering to except the streampool? I mean if you´re not moving data to or from RAM, what else do you need that bandwidth for?
It´s not like the CPU And Tempest commands requires huge bandwith to pull off.
And even if maybe PS5 has more dedicated hardware, it doesnt mean that the XSX is less prone to filling that bus. It too has to load stuff into memory.
Ofc some shader programs could use bandwidth, but you certainly would try to awoid that if you know the bus is strained already from other tasks. They profile their code quite heavily to avoid things like this.
